Abstract

The invention provides an ultrasonic inspection device which can accurately inspect the end part of an object to be inspected with less effort. The ultrasonic inspection device is an ultrasonic inspection device in which an object to be inspected is disposed between a transmission unit and a reception unit which are disposed at a distance from each other, and the reception unit receives ultrasonicwaves transmitted from the transmission unit to inspect the object to be inspected. The ultrasonic inspection device comprises a restricting unit that restricts a second propagation path different from a first propagation path of the ultrasonic wave that has passed through the object to be inspected and arrived at the receiving unit, from among propagation paths of the ultrasonic wave that has passed through the transmission unit and arrived at the receiving unit.

Description

technical field

[0001] The present invention relates to an ultrasonic inspection device for inspecting, for example, the presence or absence of peeling of a joined portion in a packaging container formed by joining sheet members. Background technique

[0002] Conventionally, soft canned foods, drinking water, etc. are stored in a bag-type packaging container in a sealed state. This packaging container is formed into a bag shape by joining peripheral edge portions of sheet members (including film members) by welding, adhesive bonding, etc., and after accommodating contents inside, the opening is joined. In such a packaging container, if peeling or the like occurs at the junction, the content contained in the packaging container may leak, and therefore, the junction is inspected during the manufacturing stage.

[0003] In this inspection, for example, an ultrasonic inspection device is used. An ultrasonic inspection device transmits ultrasonic waves to a packaging container ...

Embodiment approach

[0039] First, an embodiment will be described.

[0040] figure 1 It is a block diagram showing a configuration example of the ultrasonic inspection system 1 according to the embodiment. The ultrasonic inspection system 1 inspects an inspection object 40 using ultrasonic waves. exist figure 1 In the illustrated example, the ultrasonic inspection system 1 includes a display device 10 , an ultrasonic inspection device 20 , and a transport device 30 .

[0041] The display device 10 displays various information related to ultrasonic examination output from the control unit 22 of the ultrasonic examination device 20 . The various information related to the ultrasonic inspection refers to, for example, information related to the inspection object 40, the wavelength or intensity of the transmitted ultrasonic wave, the speed at which the inspection object 40 is transported, the analysis result of the received ultrasonic wave, and the determination of the presence or absence of the u...
